Zs Exclusive Vti-Tech: a strong MOT record by UK norms
Across 1,317 MOT tests, the Zs Exclusive Vti-Tech returns 89.0% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is brake pads worn below 1.5 mm. An excessively worn brake disc and a binding brake round out the top three. Average tested mileage sits at 20,804, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Buying or keeping a ZS Exclusive Vti Tech?
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
